firewall rules to allow sudo apt-get update

Posted October 11, 2020 136 views
DigitalOcean Cloud Firewalls

My DO firewall (not UFW) is set up to allow only HTTPS and SSH.

sudo apt-get update

fails with

Err:1 http://mirrors.digitalocean.com/ubuntu focal InRelease
Temporary failure resolving ‘mirrors.digitalocean.com’

but is ok when the firewall is disabled

What rules would I add to the firewall to allow 'apt-get update’ ?

Hi,
How do the outbound rules look like in your firewall’s settings ?
Default settings are like below

Type        Protocol    Port Range          Destinations    
ICMP        ICMP                         All IPv4 All IPv6
All TCP     TCP          All ports       All IPv4 All IPv6
All UDP     UDP          All ports       All IPv4 All IPv6

All outgoing traffic is allowed by default, and it is OK for most implementations.
